Method for efficiently machining tooth-shaped pattern on surface of knob mold

Abstract

The invention discloses a method for efficiently machining a tooth-shaped pattern on the surface of a knob mold. The method comprises the steps of mold design and machining, wherein the mold adopts detaching and embedding design and comprises a mold core, an insert and a sliding block, the insert and the sliding block which are matched with each other are machined respectively, and an insert hole matched with the insert and a T-shaped groove matched with the sliding block are machined in the mold core; electrode design, wherein an electrode is designed to be a single electrode, the single electrode is provided with a complete tooth-shaped pattern structure, and the electrode is machined; and sliding block assembling and positioning and discharging forming. According to the method, the single electrode is designed, one-time disassembling and assembling are conducted during discharging, repeated disassembling, assembling, correction and edge touching number searching are avoided, then manpower and material resource cost is saved, the machining precision is improved, and the purposes of reducing cost and improving efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a method for efficiently processing tooth-shaped patterns on the surface of a knob mold. Background technique [0002] With the development and progress of economic technology, cars are becoming more and more popular, and most of the cars are equipped with knobs, which can be used as control buttons to control and adjust gears, air conditioners, and multimedia. The surface of the knob is often provided with tooth-shaped patterns, which mainly play the role of increasing friction, increasing touch and adjusting the feel. [0003] Mold molding is often used in the manufacture of knobs, among which, the processing of the tooth pattern on the knob mold has become a key point and a difficult point. Most of the current processing of the tooth pattern on the mold adopts electrode discharge machining, and the mold includes a mold core and a slider. There are four slider...

Problems solved by technology

The existing processing method has the following defects: one is that the number of electrodes is large and the number of disassembly and assembly is many, each time the electrode and the slider are replaced, it needs to be re-calibrated and the number of touches is divided, which greatly reduces the production efficiency; the other is that due to Electrodes and sliders need to be disassembled and calibrated many times, resulting in an increase in the cumulative error of processing and affecting the appearance and accuracy of the product
